When to choose market foreclosure and vertical mergers with substitutable final products

PurposeBased on the idea of part standardisation and product differentiation in lean management, this paper answers the question when integrate firms should choose market foreclosure to maximise profits by studying a two-tier supply chain, which contains three types of firms: suppliers, manufacturers and integrated firms. Moreover, the effect of the substitutability between final products and the competition among firms in the supply chain would be investigated from the perspective of dynamic analysis.Design/methodology/approachConsidering the decision order of integrated firms and manufacturers in the downstream of the supply chain, the authors build three competition models. In each model, integrated firms compete with manufacturers in Bertrand–Nash fashion. And, suppliers compete with each other in Cournot fashion, so do integrated firms and manufacturers. The authors further discuss how the competitive relationship between firms affect the equilibrium result.FindingsNumerical analysis reveals that under other conditions unchanged, the increased competition between downstream firms leads to the rise in the willingness of selling parts for integrated firms, while the increase in the number of suppliers has the opposite effect. In addition, due to the market change before and after the vertical merger, it may lead to the transition from profitable to unprofitable for the vertical merger.Originality/valueThis paper provides a theoretical analysis and managerial implication for integrated firms' market foreclosure decision. From the perspective of dynamic analysis, this paper demonstrates the result of vertical mergers and provides an explanation for the failure of vertical mergers.

Pricing Strategies of Food Retailers

Studies examining pricing outcomes in the food retail industry are complicated both by the multiproduct nature of transactions and by the presence of highly concentrated food processing and retailing industries that mediate between relatively competitive farm product markets and the consumer market. In this review, we examine theoretical and empirical evidence for retail pricing and the vertical relationships that have emerged among retailers, food manufacturers, and farmers. We first focus our analysis on consumer behavior in multiproduct retail markets, including consumer search, habit formation, and reference pricing, and then discuss retail market outcomes for price discrimination, price fairness, and price obfuscation. We then turn to relationships between retailers and food manufacturers through bargaining outcomes, market foreclosure, and slotting allowances, and discuss the resulting implications for retail-price pass-through.
